The SM1610-4 is standard equipment for both the US Navy and US Coast Guard, providing industry-leading AIS reception sensitivity and monitoring range. The SM1610-4 also includes VDL analysis capabilities; making it a valuable tool for port administrations.
The wide adoption of AIS has caused frequency congestion in many ports. The SM1610-4 provides analysis tools to measure the health of the VDL and aid in determining the total number of slots used, garbled packets and packet collisions. Defective or malfunctioning AIS devices degrade the success of an entire AIS environment; identifying non-compliant transponders is key to a healthy system.
The SM1610-4 also enables administrations to monitor AIS transponders for IMO1252 compliance. The SM1610-4 measures frequency, deviation and slot timing (jitter) of every packet received; quickly pinpointing suspect transponders for inspection. On-site inspections are time consuming and expensive for everyone; remote inspections using the SM1610-4 can save time and money.
